Do I need an 8-electrode scale or is a 4-sensor smart scale enough?

Eight-electrode models with handles (Arboleaf, RENPHO MorphoScan, GE Body Pod) send current through both the upper and lower body, which reviewers say produces more stable, segmental readings than foot-only scales. Specialist communities still caution that even 8-electrode consumer scales drift from DEXA, but several r/loseit and r/BuyItForLife posters call the readings more consistent day-to-day, which is what matters for tracking change over time.
